I have tinted them with Nightshades in the past and been pulled over and asked to remove them, but I had also just kinda evaded the cop and prevented myself from getting a moving violation (parked and got out of the car before his lights came on)
The overlays look like a solid option to me, I like the red and have red supertones so I think it will be an excellent contrast, then throwing a lip on and doing something with the god awful blue Subaru emblem hahaha (it's not horrible but it sure as hell doesn't match)
